On the browser, from the tackle bar, what syntax, prefix, and suffix do I want so as to add to the above on-line hyperlink, to have the ability to entry this submit edit web page (I’ve admin rights).
None, no such prefixes/suffixes/additions exist. It is not attainable out of the field to do that.
To do that you would wish to know the ID of the submit to generate the edit URL, and your URL doesn’t comprise a submit ID.
Edit hyperlinks take this type in commonplace WordPress:
wp-admin/submit.php?submit={POST ID GOES HERE}&motion=edit
E.g.
wp-admin/submit.php?submit=123&motion=edit
They may also be filtered by plugins, so a theme or plugin could not use that format.
If you would like to have the ability to take any URL and switch it into an edit URL utilizing solely that URL, you’ll need to jot down extra code that redirects the consumer to the edit web page.
